From what I’ve read it sounds like a dysfunctional family situation but too bad. If you have kids you are responsible for them.
I do think the fbi dropped the ball to some degree but to what extent I can’t say. I do not know how many tips or calls they get like this but I’d guess it’s a high number. Can they be responsible for keeping tabs on everyone who they get info on? I don’t know. I’d say it depends on the number. The fbi likes to push blame and responsibility off onto local agencies that in most cases are probably understaffed and overworked. I think In alot of cases there’s prior intel that comes in on these people who end up doing these mass shootings. Someone should be keeping tabs on them but who is the question. It’s easier said than done. I don’t have an answer but it’s a serious enough issue in our society that it needs to be figured out. Jmho.
